free rotary movement in the,valve, and is screw threaded at its u perend, which vthreads mesh with interna screw threads in a'sleeve or block13, the latter screwed into theupper end of the barrel `extension 5, andinclosed by a capk 14 screwed `on t0 the upper end of the extension.

l .A knob or hand hold is secured on the upper end of the stem, and byturning the same, the valve 8 can be raised and lowered to regulate theiiow of water, and it will be observed,particularly by reference to Fig.4, that the valve is of appreciably smaller diameter than is the pipe,so that when it is elevated above its seat, water will pass around thesides ofthe valve and Will be permitted a free circulation.l

Fig. 2 illustrates my improved hydrant in connection with an ordinarymetal casing 16, while Fig. 3 illustrates the device employing anordinary wooden casing 17. In other respects, the construction isidentical with that described in connection with Fig. 1.

Various slight changes might be made in -the general form andarrangement of parts described Without departing from my invention, andhence I do not restrict myself to the precise details set forth, butconsider myself at liberty to make such changes and alterations asfairly fall withinthe spirit and scope yof the claims.

' Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. In a hydrant, the combination with a barrel, a valve seat, avertically movable Avalve in said barrel, a stem secured to said valveand projecting up through the barrel, semi-cylindrical guides, curvedtongues on the opposite sides of said valve movable in said guides, adrain pipe communicating With said kbarrel-in one of saidsemicylindrical guides and so positioned as to be closed -by one of saidcurved tongues when the valve is moved to open position, and be openwhen `the valve is moved to closed position.

2. In a hydrant, the combination with a barre ,.a valve seat, avertically movable Yvalve in said barrel, a stem secured to said valveand projecting up through the barrel, semi-cylindrical guides, curvedtongues on the oppositesides ofr said valve movable in said guides, adrain pipe communicating with said barrel in one of saidsemi-cylindrical guides and so positioned as to be closed by one of saidcurved tongues when the valve To all whom it may concern:

Be it known that I, `Lawis M. LANoAsTER, a citizen of the United States,residing at county of Philadelphia Philadelphia, 1n the and State ofPennsylvania, have invented certain new and useful `Improvements inHydrants, of which the following is a speci-A iication.

My invention relates toimprovements iny hydrants, the object of theinvention being to provide a simple, inexpensive construc-V tion ofbarrel with improved valve mechan-` ism for closing the lower portionofthe barrel positioned lbelow the .ground level far enough to preventfreezing, andfor automatically opening an outlet from the barrel` todrain the same when the valve is closed, and for closing said outletwhen the valve is o en.

pWith these and other objects in view, the invention consists in certainnovel features of construction, and combinations and arrangements ofparts as will be more fully hereinafter described and pointed out in theclaims.

In the accompanying drawings, Figure 1, is a broken view partly inelevation, and partly in vertical section illustrating onel form of myimprovements. Figs. 2 and 3 are similar views showing the application ofmy improved hydrant in connection with a metal and a Wooden casingrespectively. gig. 4, is a view in section on the line 4-4 of 1represents the hydrant barrel, whichis an ordinary pipe externally screwthreaded at its ends, and connected by a cou ling 2 at' its lower endwith the water supplly pi e 3. The upper end of barrel 1 is connected ya coupling 4, with an extension 5, and a spout 6 is screwed into saidcoupling.

valve seat 7 is rovided in the water pi e 3, and is norma ly closed by asliding va ve 8, which latter is provided at op osite sides with roundedtongues 9, movagle in semi-cylindrical guides 10 in the pipe 3, so as.to guide the valve in its up .and down movement, and direct the sameacross a drain pipe 1`1, located above the normal closed-position of thevalve, so that when the valve is on its seat, thedrain pipe will be opento drain the barrel, and when the valve is moved to open position, thedrain will be closed, as will be readily understood. vThis valve 8 ismade with a cylindrical bore to receive the valve stem 12, which latterhas is moved to open position, and be open when the valve 1s moved toclosed position, a spout on said barrel, a screw threaded bloel 1n saidbarrel, and screw threads on said stem meshing with said bleek, wherebywhen said stein is turned the valve will be moved.

3. In a hydrant, the combination with a barrel, a valve seat, avertically movable valve in said barrel, a stern secured to said valveand projecting up through the barrel, semieylindrieal guides, Curvedtongues on the opposite sides oi' said valve movable in said guides, adrain pipe communicating with said barrel in one of saidsemi-cylindrieal guides and so positioned as to be closed l l l l l byone o'l said curved tongues when the valve is moved to open position.and be opened when the valve is moved to elosed position, a spout onsaid barrel, a serew threaded bleek in said barrel, and serew threads onsaid stein meshing with said block, whereby when said stem is turned thevalve will be moved7 and a easing inelosing said barrel.

1n testimony whereoll have signed in v name to this speei'lieation inthe presence ol two subseribing witnesses.
